Radiation

Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Radiation is classified as either ionising or non-ionising depending on whether or not it has sufficient energy to cause atomic changes in the matter through which it passes. Both kinds of radiation are found in the environment and exposure may occur as a result of both natural and anthropogenic processes.

New ionising radiation imaging and treatment modalities are increasingly used in both diagnostic and therapeutic procedures in many areas of medicine, and understanding potential risks to health of both patients and medical staff are paramount in maximising the efficacy of treatments while ensuring their safety.

Similarly, increases in the application of non-ionising radiation as a means of transmitting data—for example, to improve industrial applications and mobile communications—have raised concerns about potential risks of a number of cancer and non-cancer health outcomes, but mechanisms explaining such associations are largely missing.
